a. Complete the sentence. The college town race is ___% of the hometown race in length.
To complete the sentence, put both distances into the same units, and then find the ratio. In this case, it might be easiest to convert both distances to feet since it is known that 1 meter
3.28084 feet and 1 mile
5280 feet, rounding to two decimal places as needed.

Find the ratio of the distance of the college town race to the distance of the hometown race, rounding to two decimal places as needed.
.

4970.47 ft
26400.00 ft
0.19
Then multiply by 100 to change it from a decimal to a percent. The college town race is % of the hometown race in length.
0.19

b. Consider the student's personal records shown in the table for the two races. What is the student's average speed in each race in miles per hour? To find the average speed in miles per hour, convert the student's time to hours. Begin by using the conversion 1 second
60 fractional seconds to convert seconds:fractional seconds

Finally, divide the answer by 60 to convert from minutes to hours. This is the amount of time it took, in hours, to run the race. Round to two decimal places.

To find the speed, divide the distance of the race by the time it took to run the race, rounding to two decimal places as needed. mi/hr

To find the average speed during the college town race, take the time it took to complete the race and follow the steps above to figure out how many hours it took to run the race, rounding to two decimal places as needed.
hr
32:56:00 = 0.55
The college town race was of the hometown race in length. So, the college town race was miles long. Divide this value by the amount of hours it took to run the race. This will give the average speed during the race in miles per hour, rounding to two decimal places as needed.

Therefore, the student's average speed during the hometown race was mi/hr and the average speed during the college town race was mi/hr.
8.47
1.73
c. What is the average speed in each race in miles per hour for the other students?
To solve this part, redo the previous steps using the other students' times from the table. Find the average speed in miles per hour for each race, rounding to two decimal places as needed.
The other students' average speed during the hometown race was mi/hr, and the average speed during the college town race was mi/hr.
7.69
1.53
d. If the average speed for the college town race were run for the entire length of the hometown race, would the student beat his personal record? Answer for both the student and the other students. Compare the average speed run in either race. If the average speed run during the college race is greater than that of the hometown race, then running the hometown race at that particular speed will result in a better time. If the average speed run during the college race is less than that of the hometown race, then running the hometown race at that particular speed will result in a worse time.
If the student runs the hometown race at the same average speed as in the college town race, he beat his personal record. If other students run the hometown race at the same average speed as in the college town race, they beat their record time.

Measuring the height of a California redwood tree is very difficult because these trees grow to heights of over 300 feet. People familiar with these trees understand that the height of a California redwood tree is related to other characteristics of the tree, including the diameter of the tree at the breast height of a person. The data in the table represent the height (in feet) and diameter (in inches) at the breast height of a person for a sample of 21 California redwood trees.
Interpret the meaning of the coefficient of determination in this problem.
Perform a residual analysis on the results and determine the adequacy of the model.
Determine whether there is a significant relationship between the height of redwood trees and the breast height diameter at the 0.05 level of significance.

An amusement park studied methods for decreasing the waiting time (minutes) for rides by loading and unloading riders more efficiently. Two alternative loading/unloading methods have bee
proposed. To account for potential differences due to the type of ride and the possible interaction between the method of loading and unloading and the type of ride, a factorial experiment was
designed. Use the following data to test for any significant effect due to the loading and unloading method, the type of ride, and interaction. Use a 0.05.

Collect a set of data with at least 30 data points. The data should be quantitative, which means that it should be measured using
numbers. You can be as creative as you'd like, but here are some suggestions for things that you can survey.
• the heights of a large number of people
• the number of pages in a set of books on a bookshelf
• the number of hits earned by different professional baseball players in a season
Or if you prefer you can use the data below:
Tik Tok videos viewed by a student over 30 days:
7, 11, 6, 8, 8, 10, 7, 6, 13, 7, 6, 9, 11, 8, 14, 8, 5, 8, 6, 12, 3, 10, 8, 5, 9, 4, 9, 10, 12, 7
